Early next year, the Supreme Court will hear oral arguments in a pair of cases, which could overrule the Chevron doctrine and thereby end nearly forty years of judicial deference to federal administrative agencies’ interpretations of statutes they administer. While the cases involve regulatory compliance costs imposed on Atlantic herring fishermen, the Court’s decision will have broad and significant consequences, including the outcome of a pending appeal involving the extent to which an electric utility is obligated to purchase all the output from a renewable energy generator.

Without Specific Statutory Authorization, Agency Tells Fishermen to Pay for Monitors

Congress enacted the Magnuson-Stevens Fishery Conservation and Management Act to conserve coastal fishery resources, but also to promote commercial and recreational fishing.[1] The Secretary of Commerce, in particular her designee the National Marine Fisheries Service, promulgates regulations that implement the Act. The Service issued a rule outlining how and when New England herring fishing vessels must carry and pay for an on-board monitor, a cost which the Service recognizes will reduce fishing vessel profits by approximately 20%.[2] Several fishermen objected and sought judicial review: one group filed suit in Washington, DC, the other in Rhode Island.

In each case, the fishermen argued that the Service exceeded its authority, because the Act contains no language authorizing the Service to force fishermen to pay for the salaries of monitors. Neither case made it to trial: each court granted the Service’s motion for summary judgment, after invoking the Chevron doctrine and determining that the Act’s authorization of the Service to act as “necessary and appropriate” was sufficient to withstand the fishermen’s claims.[3] The fishermen appealed to the DC Circuit and First Circuit, where they lost again.

Citing Chevron, a split DC Circuit panel explained: “When Congress has not ‘directly spoken to the precise question at issue,’ the agency may fill this gap with a reasonable interpretation of the statutory text.”[4] The DC Circuit also noted: “When an agency establishes regulatory requirements, regulated parties generally bear the costs of complying with them.”[5] The First Circuit echoed the DC Circuit’s analysis, then concluded: “we have no trouble finding that the Agency’s interpretation of its authority to require at-sea monitors who are paid for by owners of regulated vessels does not ‘exceed[] the bounds of the permissible.'"[6] 

Each group of fishermen filed a petition for a writ of certiorari, presenting multiple issues on appeal. The Supreme Court granted each petition, but only to address one issue: “Whether the Court should overrule Chevron or at least clarify that statutory silence concerning controversial power expressly but narrowly granted elsewhere in the statute does not constitute an ambiguity requiring deference to the agency.”[7] Oral arguments on the cases – Loper Bright Enterprises v. Raimondo (Secretary of Commerce) and Relentless, Inc. v. Department of Commerce – will be held in tandem in the January 2024 argument session.

Chevron Doctrine

In Chevron, U.S.A., Inc. v. Natural Resources Defense Council, Inc.,[8] the Supreme Court established a two-step process to determine if a court should defer to a federal agency decision:      

1.  If the statute is clear (on its face or by using interpretive tools, e.g., rules of statutory construction), the court must give effect to the unambiguous, stated intent of Congress.

2.  If the statute is silent or ambiguous, an agency’s reasonable interpretation of the statue is entitled to deference.

The doctrine is limited. Although deference can be afforded to a federal agency’s formal “notice and comment” rulemaking proceeding under the Administrative Procedures Act, non-binding agency guidance, such as policy statements, are not entitled to deference.[9] Likewise, the Supreme Court has never “deferred to an agency’s conclusion that state law is preempted.”[10] 

Significantly, last year the Supreme Court in West Virginia v. EPA did not defer to the Environmental Protection Agency’s reading of the Clean Air Act, but rather struck down EPA’s Clean Power Plan by invoking the major questions doctrine.[11] The antithesis of deference, the major questions doctrine requires a federal agency to show “clear congressional authorization”[12] when claiming the power to make decisions of vast “economic and political significance.”[13] Notwithstanding the above, application of the Chevron doctrine often results in a court’s upholding a federal agency’s action, which in turn deters legal challenges to administrative orders.

Pros and Cons

Supreme Court Justice John Paul Stevens, who wrote the Chevron opinion, gave three reasons for establishing the doctrine. One, by not specifically addressing an issue, Congress implicitly vests an agency with a limited delegation to act (reasonably). Two, agencies (rather than courts) have greater institutional competence and expertise in an esoteric subject matter. Three, the executive branch of government, not the judicial branch, should make policy choices.[14]

Justice Elena Kagan has expressed her support for the doctrine this way: “Members of Congress often don’t know enough— and know they don’t know enough—to regulate sensibly on an issue. Of course, Members can and do provide overall direction. But then they rely . . . on people with greater expertise and experience. Those people are found in agencies.”[15]

However, Justice Neil Gorsuch contends that the doctrine is unfair: “[O]ur courts have long and often understood that, ‘as between the government and the individual, the benefit of the doubt’ about the meaning of an ambiguous law must be ‘given to the individual, not to authority….'" [16] Yet, he claims that the Chevron doctrine has the opposite effect: “We place a finger on the scales of justice in favor of the most powerful of litigants, the federal government, and against everyone else.”[17] He therefore concludes: “At this late hour, the whole project deserves a tombstone no one can miss.”[18]

Justice Clarence Thomas also opposes the doctrine: it forces judges “to abandon what they believe is ‘the best reading of an ambiguous statute’ in favor of an agency's construction. It thus wrests from Courts the ultimate interpretative authority to ‘say what the law is,’ and hands it over to the Executive.”[19]

Context

The 1984 Chevron opinion was unanimous, but with only six justices participating: Justices Marshall, Rehnquist, and O’Connor did not participate. Before October 13, only eight justices were scheduled to participate in the Loper Bright decision: Justice Ketanji Brown Jackson was recused, because she was on the DC Circuit panel that heard arguments in Loper Bright. However, granting certiorari to Relentless allows all nine justices (including Justice Brown Jackson) to help decide the fate of Chevron.

The Chevron doctrine was established in a case upholding a regulation promulgated by the Reagan administration’s EPA. The EPA administrator during the rulemaking was Ann Gorsuch. Her son, Supreme Court Justice Neil Gorsuch, is ardently opposed to the doctrine.

The herring fishermen have already beaten the odds by the Supreme Court’s deciding to hear their cases. Absent a few instances where parties have a right to appeal to the Supreme Court (not applicable here), an aggrieved party seeking the Supreme Court to review a lower court decision must file a petition for a writ of certiorari. “Writ” means a written command, while “certiorari” is Latin for “to be more fully informed.” By filing a request for a writ of certiorari, a petitioner asks the Court to order a lower court to send up the record of the case for review. The Supreme Court is not obligated to grant the requested review, but rather carefully chooses cases that might have national significance or harmonize conflicting circuit court decisions. If four of the nine Justices agree, the Court grants the request. Each year, the Supreme Court reportedly receives about 7,000 petitions for a writ of certiorari, but only hears oral argument for 100.

Implications

As noted above, the Supreme Court granted the fishermen’s writs of certiorari to determine whether to overrule or curtail Chevron. More and more the Court has been using the doctrine less and less, but trial and appellate courts still regularly apply the doctrine. Overruling Chevron would lift “the finger on the scales of justice ... in favor… of the federal government” and, thereby, arguably reduce the number of federal agency victories involving legal challenges to agency regulations and spur litigation objecting to the terms of administrative oversight. This could have a deleterious effect on aspects of the Biden administration’s “whole-of-government” approach to combatting climate change, such as the Securities and Exchange Commission’s proposal to require registered companies to include climate-related information in registration statements and periodic reports. On the other hand, the practical effect of the Court’s simply pruning the Chevron doctrine is unclear.

Utilities’ Obligation to Purchase Green Energy from Small Generators

This summer, the Edison Electric Institute (an electric utility trade association) and NorthWestern Energy (an electric utility in Montana) filed a petition for writ of certiorari regarding the Federal Energy Regulatory Commission’s interpretation of the Public Utility Regulatory Policies Act of 1978 (“PURPA”). PURPA requires electric utilities to purchase all the output of small power production “qualifying facilities” or QFs, which are defined by statute and regulation as renewable fuel generators with a “power production capacity” not greater than 80 MW. At issue is whether an integrated 160 MW solar project and 50 MW battery storage system qualifies as a QF, requiring NorthWestern to purchase all the QF’s energy output. FERC initially found that the solar project was not a QF because it could produce more than 80 MW.[20] On rehearing, FERC reversed course, explaining that the 80 MW limit does not apply to the amount of power a generator could produce, but rather how much could be delivered.[21] FERC reasoned that the solar developer was a QF because it intends to limit energy delivery to 80 MW: the solar array would generate direct current power, but inverters (which change the DC power from the array and the battery into alternating current power before delivery) would be designed to limit the amount of power that can be delivered to 80 MW. On appeal, the DC Circuit applied Chevron and by a two-to-one vote deferred to FERC.[22]

EEI and NorthWestern argue that the DC Circuit majority opinion misapplied Chevron, by finding that PURPA is ambiguous (because the statute does not define “power production capacity”) without performing the full Chevron “step one” analysis. The petitioners ask the Supreme Court to grant certiorari or, alternatively, delay deciding until the fate of Chevron is determined. FERC agrees. Ultimately, if Chevron is upheld, so too will FERC’s QF order.  But, if the doctrine is overruled, the Supreme Court would likely remand the proceeding to the DC Circuit to determine (without agency deference) whether FERC reasonably interpreted PURPA.

SEC Proposes Expansion of Investment Adviser Performance-Based Compensation Rule

On September 30, 2026, the Securities and Exchange Commission (the “SEC”) proposed amendments to Rule 205-3 under the Investment Advisers Act of 1940, as amended (the “Advisers Act”), which provides an exemption from the general prohibition under Section 205(a)(1) of the Advisers Act on registered investment advisers receiving performance-based compensation (the “Proposal”) so long as performance-based compensation is limited to “qualified clients”.1 Most notably for private fund sponsors, the Proposal would expand the definition of “qualified client” to include any investors that satisfy the “accredited investor” definition under Regulation D. The Proposal may also have implications for private fund managers that rely on exemptions from investment adviser registration under state law because certain state-level investment adviser registration exemptions incorporate or otherwise reference the federal qualified client definition. Expansion of the Qualified Client Definition Under the current Rule 205-3, an investor generally may qualify as a qualified client if, among other alternatives, the investor has at least $1.4 million under management with the adviser or has a net worth exceeding $2.7 million. These thresholds are higher than the financial thresholds applicable to many accredited investors under Regulation D. As a result, an investor may currently qualify as an accredited investor for purposes of investing in a private offering without qualifying as a qualified client for purposes of paying performance-based compensation. The Proposal would expand the qualified client definition to include any natural person or legal entity investor that satisfies the accredited investor definition under Regulation D. The Proposal would also remove the assets under management and net worth thresholds under the current Rule 205-3 qualified client test. For private funds relying on Section 3(c)(1) of the Investment Company Act of 1940, this change could reduce the need to apply a separate qualified client standard to investors that already qualify as accredited investors. Dorsey Observations and Next Steps If adopted as proposed, the expanded qualified client definition could be particularly significant for private fund managers. Most private fund offerings are already limited to accredited investors under Regulation D. However, the Proposal could expand the pool of prospective investors available to emerging private fund managers while reducing the regulatory burden associated with complying with Rule 205-3. The Proposal could also benefit advisers operating below the SEC registration threshold that rely on a state private fund adviser exemption. A number of states have adopted exemptions modeled on the North American Securities Administrators Association (“NASAA”) private fund adviser exemption, which may condition relief for advisers to certain funds relying on Section 3(c)(1) on each beneficial owner satisfying the federal qualified client definition. However, state requirements vary, and any effect of the Proposal would depend on the text of the applicable state exemption and how it incorporates Rule 205-3. Many emerging private fund managers may have a larger network of accredited investor relationships than qualified client relationships during the early stages of their investment advisory business. Currently, under Rule 205-3, private fund managers may receive performance-based compensation from investors who do not satisfy the qualified client definition if those investors were admitted to their private funds prior to registration with the SEC. Following registration with the SEC, however, managers may continue to permit investors that are not qualified clients to invest in future private funds but may not receive performance-based compensation from those investors with respect to such investments. In addition, because the net worth and assets under management thresholds for qualified client status are adjusted for inflation every five years, the pool of qualified client investors may diminish over time as previously eligible investors no longer satisfy the applicable thresholds. The Proposal could provide the dual benefit of greater flexibility for private fund managers to establish and maintain relationships with accredited investors as their businesses scale and they become registered with the SEC, and greater flexibility for certain accredited investors to participate in investment strategies that historically have been restricted to much larger institutional investors. Unless and until the Proposal is adopted, investment advisers should continue to comply with the existing qualified client requirements. If the Proposal is adopted, private fund sponsors should consider whether corresponding changes are appropriate for their subscription documents, investor questionnaires, and other offering materials. Advisers that are state-registered or rely on a state-level exemption should also consult the laws and regulations of each relevant jurisdiction before changing investor eligibility standards or performance-based compensation practices, because adoption of the federal amendments may not automatically modify state requirements. Comments on the Proposal will be due 60 days after publication in the Federal Register. 1 Investment Adviser Performance-Based Compensation Modernization, Investment Advisers Act Release No. IA-7022 (Sept. 30, 2026), available at https://www.sec.gov/rules-regulations/2026/09/s7-2026-28#33-11443proposed.

The Supreme Court Update - October 8, 2026

On September 29, 2026, the Supreme Court granted certiorari in one case: Department of Homeland Security v. D.V.D., No. 26-426: This case concerns the Trump Administration’s “third-country removal” procedures, where immigrants are deported to countries not listed in the removal orders. In granting certiorari, the Court granted the Government’s application to stay a lower court decision halting the practice, which will allow third-country removals to continue pending resolution of the case. The issues presented are: (1) Whether the district court had jurisdiction over respondents’ claims; (2) whether the district court had authority to enter class-wide declaratory relief and APA vacatur under 8 U.S.C. § 1252(f)(1); (3) whether the Government’s guidance on third-country removals is unlawful under 8 U.S.C. § 1231(b), the due process clause, or FARRA/CAT and its implementing regulations; and (4) such other questions that the Government determines are appropriate for the proper disposition of the case. On October 1, 2026, the Court granted certiorari in three additional cases: Rhoney v. Barbosa da Cunha, No. 26-104: Immigration officials detained Ricardo Aparecido Barbosa da Cunha—a Brazilian citizen who had lived in the United States for approximately twenty years after entering without inspection—and denied him a bond hearing under 8 U.S.C. § 1225(b)(2)(A). The Second Circuit held that his detention was instead governed by § 1226(a), which permits release on bond, because § 1225(b)(2)(A)’s mandatory-detention requirement applies only to noncitizens apprehended while entering the country or shortly thereafter. The question presented is: Whether 8 U.S.C. § 1225(b)(2)(A) mandates the detention pending removal proceedings of aliens who, like Barbosa da Cunha, are present in the United States without having been admitted. Missionaries of St. John the Baptist, Inc. v. Frederic, No. 25-113: A Catholic religious organization sought to build a shrine to the Virgin Mary on land the organization owned adjacent to its church in Park Hills, Kentucky. Local zoning restrictions prohibited the proposed construction. The question presented is: Whether a land-use regulation that prohibits a religious institution from building a religious structure on its own property constitutes a “substantial burden” on religious exercise under the Substantial Burden Provision of the Religious Land Use and Institutionalized Persons Act, 42 U.S.C. § 2000cc(a). Marschner v. Marschner, No. 25-1349: Under the Uniformed Services Former Spouses’ Protection Act (“USFSPA”), a veteran’s longevity-based retirement pay can be divided in a divorce, but retirement pay based on disability and retirement pay that was waived to receive disability pay are indivisible. The question presented is: Does the USFSPA require state courts to refuse enforcement of indemnification provisions in a divorce settlement agreement?

EPA Limits Title V Re-Litigation of NSR Permits

Overview On September 25, 2026, the U.S. Environmental Protection Agency (“EPA”) published a final rule that significantly limits the ability of third parties to use the Clean Air Act (“CAA”) Title V permitting process to revisit New Source Review (“NSR”) permitting decisions years after those decisions were made. The rule establishes that NSR permitting determinations generally must be challenged during the original permitting proceeding, thereby providing regulated sources with greater permitting certainty and finality for major capital projects. Published in the Federal Register titled Clarifying the Scope of “Applicable Requirements” Under State Operating Permit Programs and the Federal Operating Permit Program (Docket ID No. EPA-HQ-OAR-2023-0401), the rule amends 40 C.F.R. Parts 70 and 71 to codify EPA’s interpretation regarding when requirements established under other CAA programs may be reviewed, modified, or implemented through the Title V operating permit program. The rule becomes effective 30 days after publication. The rule addresses two principal issues: (1) the relationship between NSR preconstruction permitting and Title V operating permits, and (2) the treatment of the General Duty Clause under CAA section 112(r)(1). Most significantly, the rule provides greater certainty for sources navigating the NSR permitting process. EPA’s amendments are intended to ensure that NSR permitting decisions made through an approved public process are generally not revisited later through Title V permit proceedings. The rule responds to a circuit split between the U.S. Courts of Appeals for the Fifth and Tenth Circuits. In Environmental Integrity Project v. EPA, 969 F.3d 529 (5th Cir. 2020), the Fifth Circuit upheld EPA’s interpretation, concluding that it was consistent with the text, structure, and purpose of Title V. In contrast, the Tenth Circuit reached the opposite conclusion in Sierra Club v. EPA, 964 F.3d 882 (10th Cir. 2020), finding that the then-existing regulatory definition of “applicable requirement” did not support EPA’s position. By amending the regulatory language on which the Tenth Circuit relied and codifying the interpretation approved by the Fifth Circuit, EPA has established a nationwide framework governing the interaction between NSR and Title V. NSR and Title V: EPA Establishes a Uniform Nationwide Framework At the core of the rule is EPA’s effort to define the respective roles of NSR and Title V. The rule codifies the approach EPA has applied since 2017: once a source obtains an NSR permit under an EPA-approved permitting program, and that permit was issued following public notice with an opportunity for comment and judicial review, the permit establishes the NSR-related “applicable requirements” of the State Implementation Plan (“SIP”) or Federal Implementation Plan (“FIP”) for Title V purposes. Under this framework, Title V is not a vehicle for re-examining underlying NSR permitting decisions. EPA does not intend to use the Title V process to revisit applicability determinations, emissions calculations, control technology determinations, permit conditions, or other issues resolved through the NSR permitting process. This principle applies regardless of the stage of the Title V proceeding; whether the NSR permit was issued pursuant to a SIP or FIP; the type of NSR issue involved; or whether the NSR permit is incorporated into Title V sequentially or concurrently. Limited Exceptions EPA recognizes several circumstances in which NSR issues may still be reviewed through the Title V program: No NSR permit was issued at all; The permit was issued without public notice and an opportunity for comment and judicial review; or The issue involves substantive overlap between Title V and NSR requirements, such as the adequacy of monitoring provisions. As a result, the rule does not insulate unpermitted projects or foreclose review of matters that independently arise under Title V. Key Regulatory Amendments The rule revises the definition of “applicable requirement” in 40 C.F.R. §§ 70.2 and 71.2. Paragraph (1): Where an NSR permit is issued with public notice and an opportunity for comment and judicial review, the permit establishes and defines the applicable SIP or FIP requirements for Title V purposes. Paragraph (2): All NSR permit terms, including terms contained in minor NSR permits, constitute applicable requirements that must be incorporated into Title V permits. Paragraph (4): CAA section 112(r)(1) (the General Duty Clause) is expressly excluded from the definition of “applicable requirement,” while section 112(r)(7) Risk Management Program requirements remain included. EPA also amended 40 C.F.R. §§ 70.8 and 70.12 to clarify that alleged defects in requirements established outside the Title V process generally do not provide a basis for EPA objection to a Title V permit or for a Title V citizen petition. General Duty Clause Exclusion The rule also codifies EPA’s longstanding position that the General Duty Clause in CAA section 112(r)(1) is not an “applicable requirement” for Title V purposes. EPA points to several considerations supporting that conclusion, including the distinction between the General Duty Clause and Title V permit terms, the provision’s origins in the Occupational Safety and Health Act’s general duty clause, and the different enforcement structures applicable to the General Duty Clause and Title V permit requirements. Importantly, excluding section 112(r)(1) from the definition of “applicable requirement” does not eliminate EPA’s authority to enforce the General Duty Clause independently of the Title V program. The final rule instead clarifies that the General Duty Clause need not—and should not—be incorporated into Title V permits as an applicable requirement. Practical Implications for Regulated Sources Greater Finality for NSR Permits  For projects requiring PSD, nonattainment NSR, or minor NSR permits, the permitting process becomes the primary forum for resolving disputes regarding applicability determinations, emissions calculations, control technology requirements, offsets, and permit conditions. Once an NSR permit is issued through a qualifying public process, regulated sources should face substantially reduced risk that those same issues will be challenged years later through Title V permit proceedings. Reduced Risk of Collateral Permit Challenges Stakeholders have sometimes sought to use Title V permit issuance, renewal, revision, or citizen-petition proceedings to challenge underlying NSR determinations. The final rule makes clear that Title V is not the appropriate vehicle for challenging whether an applicable requirement was correctly established in the first instance. This should reduce the risk of permit delays and uncertainty associated with collateral challenges to previously issued NSR permits. The rule does not, however, eliminate all Title V challenges relating to an NSR permit. Challenges concerning the Title V permit itself—including whether it appropriately incorporates applicable requirements or contains adequate compliance provisions—remain possible. Increased Importance of the Initial NSR Proceeding Because Title V generally will not provide a second opportunity to challenge the substantive validity of an NSR determination, the administrative record developed during the NSR process becomes increasingly important. Permit applicants should ensure that applicability analyses, emissions calculations, control technology evaluations, modeling demonstrations, and supporting technical documentation are thoroughly developed during the original permitting proceeding. For significant projects, applicants may therefore have an additional incentive to identify and resolve potential permitting issues before the NSR permit is issued rather than assuming that unresolved issues can be addressed during a subsequent Title V proceeding. Potential Incentive for Broader Public Participation EPA also notes that permitting authorities may choose to provide public notice and an opportunity for comment for a broader range of NSR permits because permits issued through a qualifying public process receive the benefit of the finality framework established by the rule. Some permitting authorities may conclude that greater public participation at the NSR stage is preferable to uncertainty during subsequent Title V proceedings. Conclusion The final rule is principally a permitting-certainty measure. For sources that obtain NSR permits through a public process, EPA has substantially limited the ability of third parties to revisit underlying NSR determinations through the Title V program. As a result, regulated entities should benefit from greater finality regarding key permitting decisions, reduced risk of collateral permit challenges, and increased certainty when planning and implementing capital projects.

Energy Law: Month in Review - September 2026

Welcome to Dorsey’s Energy Law: Month in Review. We provide this update to our clients to identify significant developments in the previous month. Please reach out to any of the authors, listed above, to discuss these issues. Regulatory Developments Massachusetts Ratchets Up State and Local Regulation of AI Data Centers In early September, Governor Maura Healey of Massachusetts signed an executive order requiring that artificial intelligence data centers secure the approval of local communities as a precondition to proceeding with a given project. According to the terms of the order, data center developers will need to secure a “community benefits agreement” as a precondition to receiving permits from numerous state agencies, including the Department of Environmental Protection, the Energy Facilities Siting Board, and the Massachusetts Environmental Policy Act Office. Beyond requiring community benefits agreements, the order also mandates that developers mitigate utility costs to consumers, prohibits the use of nondisclosure agreements, and requires various state agencies to develop measures to limit data center impacts on the environment. North Carolina Regulators Decline Approval of Duke Energy Gas Turbine On September 18, 2026, North Carolina Utilities Commission (NCUC) denied Duke Energy’s application for a certificate of public convenience and necessity required to construct a gas-fueled combustion turbine at its Smith Energy Complex in North Carolina. The NCUC objected strongly to the $584 million price tag and noted that Duke appeared to be constructing the facility “based on anticipated data center customer additions.” The NCUC rejected that anticipated growth as “insufficiently reliable for the Commission to act at this point.” In rejecting Duke’s application, the NCUC also noted that Duke had signed the White House Ratepayer Protection Pledge, in which it represented that it would not shift data center costs to consumers. The NCUC observed that the record did not demonstrate how Duke “intends to adhere to its commitments under the Ratepayer Protection Pledge with regard to the Proposed Facility.” Notably, commission staff had actually supported the construction of the turbine, citing concerns about Duke’s reserve margins. The NCUC noted that it “understands the Public Staff’s expressed concerns,” but those concerns were outweighed by the NCUC’s reservations, including questions of demand. Department of Energy Approves Funds for Grid Improvement The U.S. Department of Energy (DOE) recently announced that it would fund 31 grid-improvement projects in 26 states. The funding initiative is part of the DOE’s “SPARK” initiative. The funding will include $1.9 billion in federal funding from DOE and $3.35 billion in recipient cost-sharing funding. The funds will go to projects designed to improve grid reliability and lower electricity costs. Recipients plan to reconductor over 1,500 miles of transmission lines and will deploy grid-enhancing technologies across approximately 21,000 miles. DOE stated that this initiative will make available over 23 additional gigawatts of electricity. Texas Moderates Rules Governing Data Center Interconnection The Texas Public Utility Commission adopted new regulations governing large-load interconnections. The rules impose a flat study fee of $100,000 for all proposed interconnections, which departs from the initial proposal to impose study fees using a tiered system based on project size. Additionally, the final rule eliminates the PUC’s previous proposal to impose a non-refundable interconnection fee of $50,000 per MW of contracted peak demand. The final rule also moderates the initially proposed regulations governing Electric Reliability Council of Texas (ERCOT) notifications for large-load customers’ non-utilized capacity. The proposed rules would have required notifying ERCOT within 30 days of missing a scheduled energization milestone by six months. The final rules, however, do not require informing ERCOT unless a scheduled energization milestone is missed by 24 months. FERC Denies TransAlta 202(c) Cost-Recovery Plan The Federal Energy Regulatory Commission (FERC) recently rejected TransAlta’s plan to recover $19.9 million in expenses stemming from a DOE order in which DOE prohibited TransAlta from retiring its coal-powered Centralia power plant. TransAlta had previously intended to retire the facility at the end of 2025. TransAlta’s cost recovery plan proposed spending an additional $23 million on repairs to continue operating the unit. FERC’s main objection had to do with geographic scope. TransAlta’s recovery plan called for recovering costs from California Independent System Operator (CAISO) and the Southwest Power Pool (SPP), but the DOE’s order requiring operation of the plant was designed to ensure reliability in the Northwest assessment area (Montana, Oregon, Washington, and parts of northern California and northern Idaho). Accordingly, FERC was unwilling to allow cost recovery from CAISO and SPP when the order that precipitated the additional costs only related to the Northwest assessment area. FERC informed TransAlta that it would only approve cost recovery from load-serving entities in the Northwest assessment area. FERC’s decision comes amid a rush of DOE emergency orders requiring the continued operation of coal-fired generating units. Litigation Appeals Court Upholds Washington Hydropower Plant With Caveats In a September 21, 2026, opinion, the Washington Court of Appeals largely upheld a Clean Water Act water quality certification by the Washington Department of Ecology for the Goldendale Energy Storage Project, a proposed pumped-water storage hydropower system adjacent to, but off-stream from, the Columbia River. A nonprofit (Columbia Riverkeeper) and the Confederated Tribes and Bands of the Yakama Nation appealed the certification, contending that it failed to impose necessary conditions and monitoring requirements to protect the water quality of the Columbia River. Most saliently, the plaintiffs argued that the project had the potential to leak 100 acre-feet of water per year into tributaries of the Columbia River. The Court of Appeals broadly rejected plaintiffs’ challenge to the state’s conclusion that “the project was designed not to leak.” That said, the Court of Appeals did reverse on one narrow issue. Specifically, the court determined that the state’s conclusion that “leakage from the project’s tunnels would be monitored and reported” was not supported by the evidence because the certification “does not explicitly require monitoring and reporting to determine whether there is any leakage.” Accordingly, the court remanded the matter to the state to impose monitoring and reporting requirements but otherwise affirmed the certification. Legislative Developments California Legislates Restrictions on Data Center Energy Use and Grid Costs On September 21, 2026, California Governor Gavin Newsom signed seven bills broadly regulating data centers in the state. SB 1168 directed the California Public Utilities Commission to assess the energy used by data centers. It also requires the PUC to pass costs of transmission and distribution upgrades and load increases on to data centers, rather than customers. SB 886 and SB 887 compel data centers to pay for infrastructure upgrade and generation costs, and wildfire mitigation costs, in addition to imposing environmental review. The statutes additionally increase local oversight of data centers. AB 1577 imposes a monthly reporting requirement that requires data centers to supply energy consumption and efficiency data to the California Energy Commission. AB 2383 contains incentives for data centers to use onsite clean energy generation. Finally, AB 2469 and AB 2619 require data center developments to assess water supply and develop a water scarcity plan. The statutes also mandate statewide water reporting as a precondition to obtaining and renewing business licenses.
